Senior Mobile Engineer

Groupon is a marketplace where customers discover new experiences and services everyday and local businesses thrive. To date we have worked with over a million merchant partners worldwide, connecting over 16 million customers with deals across various categories. In a world often dominated by e-commerce giants, we stand out as one of the few platforms uniquely committed to helping local businesses succeed on a performance basis.

Groupon is on a radical journey to transform our business with relentless pursuit of results. Even with thousands of employees spread across multiple continents, we still maintain a culture that inspires innovation, rewards risk-taking and celebrates success. The impact here can be immediate due to our scale and the speed of our transformation. We're a "best of both worlds" kind of company. We're big enough to have the resources and scale, but small enough that a single person has a surprising amount of autonomy and can make a meaningful impact.

Groupon is embarking on a greenfield initiative to rebuild our mobile app from the ground up. We're looking for an AI-native engineer — someone who doesn't just code, but thinks creatively, challenges the status quo, and can back their ideas with data. This role calls for an independent, proactive developer who knows how to use AI tools effectively while also recognizing where human judgment and deep engineering experience matter most.

This is not a maintenance role. You'll be driving the build of a brand-new application on React Native (Expo) with a completely new GraphQL API, owning solutions end-to-end: analyzing problems, designing technical approaches, and implementing features. Our environment is fast-moving, our systems are complex, and solving problems often means stepping outside your comfort zone and collaborating across teams.

• Framework: React Native (Expo)
• Language: TypeScript, Swift, Kotlin (Native Modules)
• API: GraphQL (Apollo Client)
• State Management: Apollo, Zustand
• UI: Component-driven architecture, Nativewind
• Testing: Jest, React Native Testing Library, Detox for E2E
• Build & Release: Fastlane, GitHub Actions, CI/CD pipelines
• Observability: Sentry, Crashlytics, Grafana

• Drive the greenfield development of Groupon's next-generation mobile application
• Own end-to-end delivery: analyze problems, design solutions, and implement features
• Architect scalable and performant mobile solutions leveraging Expo and GraphQL
• Collaborate across teams (backend, infrastructure, product) to solve cross-cutting issues
• Investigate complex system behavior beyond the app layer when needed
• Ensure code quality, performance, and reliability through testing and observability
• Stay ahead of mobile best practices and advocate for improvements in developer experience
• Act as a proactive, self-directed contributor in a fast-paced environment

• Strong expertise with React Native and modern mobile app development patterns
• Proficiency in TypeScript and GraphQL (Apollo experience a plus)
• Experience delivering production-grade mobile apps (iOS and/or Android)
• Strong problem-solving skills with ability to independently drive solutions
• Familiarity with testing frameworks and CI/CD pipelines for mobile apps
• Ability to adapt quickly to new challenges and work outside comfort zones

• Experience with Expo
• Understanding of mobile app performance, profiling, and monitoring
• Prior experience with greenfield projects or system migrations
• Knowledge of observability tools (Sentry, Grafana, or similar)
• Background in collaborating with distributed and cross-functional teams
• Knows how to make the most of AI tools — using them where they add real value, but not getting caught up in hype

• Build a brand-new app from scratch on a modern mobile stack
• Direct impact on millions of users engaging with Groupon's marketplace
• Work directly with engineering leadership on high-impact, strategic initiatives
• Access to cutting-edge AI tools, with freedom to experiment responsibly
• The stability and visibility of working at a NASDAQ-listed company
• An open and transparent data culture, where insights are shared and trusted to guide decisions
